Iceland has one native land mammal, no snakes and almost no mosquitoes, but its seas and cliffs are full of life. Here is which animals you can see, where and when.
Ask a first-time visitor what animals they expect in Iceland, and you will hear polar bears, wolves and maybe a moose. The real answer is stranger and better. Iceland has just one native land mammal, a small fox that walked here across the sea ice at the end of the last Ice Age. Everything else either swims, flies or arrived on a Viking ship.
The animals you can realistically see in Iceland are puffins and other seabirds, whales, dolphins and seals, the Arctic fox, reindeer in the east, and the country's famous horses and sheep. There are no snakes, no native reptiles or amphibians and, until very recently, no mosquitoes. Polar bears do not live here, although a handful have drifted ashore over the centuries.
What animals live in Iceland?
Iceland's wildlife is shaped by isolation. The island rose from the Atlantic as a volcanic landmass and has never been connected to a continent, so land animals could only arrive by sea ice, by swimming, by flying or with people. That leaves a short list of land mammals and a very long list of birds and marine life.
Here is the quick summary:
The Arctic fox, the only native land mammal
Reindeer, mink, mice and rats, all introduced by people
Icelandic horses, sheep, goats, cattle and dogs, with roots in the settlement era
More than 20 species of whales and dolphins, plus harbor and gray seals
Dozens of breeding bird species, including Atlantic puffins, Arctic terns and eiders
If wildlife is high on your list, think coast rather than interior. The sea and the bird cliffs are where Iceland is truly rich in animal life.
The Arctic fox, Iceland's only native land mammal
The Arctic fox (melrakki in Icelandic) is the only land mammal that reached Iceland on its own. Foxes most likely crossed on sea ice during the last Ice Age and have lived here ever since. They come in two color types: a white form that turns brown-gray in summer, and a "blue" form that stays dark all year.
Foxes live across the country, but they are shy and hard to spot in most places. The best chance is in the Westfjords, especially the remote Hornstrandir Nature Reserve, where hunting is banned and foxes have grown far less wary of people. The Arctic Fox Center in Súðavík, near Ísafjörður, runs exhibitions and research on the species and is a good first stop. A Westfjords expedition puts you in the region where your odds are best.
How to spot an Arctic fox
Arctic foxes are small, roughly the size of a house cat with a bushy tail, and they are most active around dawn and dusk. Along the coast, they feed on seabirds, eggs, fish and carrion washed up on the shore, while inland they hunt ptarmigan and small rodents. In winter, their white coats make them nearly invisible against the snow.
If you do spot one, stay still and let it come to you. Foxes are naturally curious, especially young ones in late summer, and they will often circle closer if you are quiet. Never feed them, because foxes that associate people with food can become a nuisance and are more likely to be hit by cars.
Reindeer in East Iceland
Reindeer are not native to Iceland. They were brought over from Norway in the late 18th century, when the authorities hoped they would become a new source of food and income. According to the Arctic Council's CARMA reindeer herd overview, about 35 animals were released in the northeast in 1787, and today's wild herd descends from a small founding group like this.
Unlike reindeer in Scandinavia, Iceland's herd is wild, not herded. The animals live only in East Iceland, roaming the highlands in summer and moving down toward the coast and lowlands in winter, when they are easier to see. The herd numbers in the low thousands, and hunting is tightly controlled through annual quotas. Visiting the Eastfjords and the Fljótsdalur valley in winter or spring gives you the best chance, and cruise passengers calling at Seyðisfjörður can join a trip into reindeer country in the Eastfjords.
Mink and other introduced animals
The American mink is the most notorious newcomer. Mink were brought to Iceland for fur farming in the 1930s, and escaped animals soon spread around the country. They prey on nesting birds and fish, and they are hunted as an invasive species. You might glimpse one darting between rocks along a river or the shore.
House mice, wood mice and brown rats arrived with ships over the centuries and live mostly near farms and towns. Rabbits, released from captivity, live in a few places, including parts of Reykjavík's green spaces. None of these animals are likely to feature in your photos, but they are part of how people have changed Iceland's small, isolated ecosystem.
Are there polar bears in Iceland?
No, there are no resident polar bears in Iceland. Occasionally a bear drifts over from Greenland on sea ice, usually reaching the north or northwest coast. The Icelandic Institute of Natural History has records of just over 600 polar bears arriving since human settlement, and since 1951 a bear has been observed on average about every other year.
Because a hungry polar bear is a serious danger to people and livestock, those that come ashore have usually been shot, which is controversial in Iceland. For visitors, the practical answer is simple. You will not see a polar bear in Iceland, and you do not need to worry about meeting one on a hike.
Puffins and seabirds
Iceland is one of the best places in the world to see seabirds, and the Atlantic puffin is the star. A large share of the world's Atlantic puffins breed in Iceland, nesting in burrows on grassy cliff tops from late spring until about mid-August. They spend the rest of the year far out at sea.
Good puffin spots include Dyrhólaey and Reynisfjara near Vík, the Westman Islands, Látrabjarg in the Westfjords and Borgarfjörður Eystri in the east, where a viewing platform puts you within a few meters of the birds. Boat trips from Reykjavík also pass puffin islands in summer. In the Westfjords, a puffin island trip near Ísafjörður visits Vigur, a small island known for its puffins and eider ducks.
Other birds to look for
Puffins get the attention, but Iceland's bird list is long. Arctic terns, which migrate between the Arctic and Antarctic each year, nest in large colonies in summer and fiercely dive at anyone who walks too close. Common eiders gather along the coast, and their down has been collected sustainably by Icelandic farmers for centuries.
Bird cliffs also hold guillemots, razorbills, fulmars and kittiwakes. Inland, look for golden plovers, whose call is a traditional sign of spring, and whooper swans on lakes. The gyrfalcon, a traditional symbol of Iceland, is rare but present, and the white-tailed eagle survives in small numbers around Breiðafjörður.
Whales and dolphins
More than 20 species of whales, dolphins and porpoises have been recorded in Icelandic waters, which makes Iceland one of Europe's top whale watching destinations. The species you are most likely to see are minke whales, humpback whales, white-beaked dolphins and harbor porpoises. Blue whales, fin whales, orcas and sperm whales are seen less often and depend on the season and location.
Whale watching runs year-round from Reykjavík's Old Harbour, with the calmest seas and the most species in summer, which makes it the easiest option if you are based in the capital. In the north, Húsavík and Eyjafjörður near Akureyri are famous for humpbacks, and whale watching in Eyjafjörður often finds them feeding close to shore.
Where and when to see whales
Summer, from about April to October, is the main whale watching season, when food is plentiful and seas are calmer. Humpbacks are the most reliable large whales around Iceland, and in winter, some humpbacks and orcas follow herring into fjords on the west coast. Dolphins and porpoises are common year-round.
If you want to photograph whales, a whale photography workshop from Reykjavík gives you time on deck with a guide who knows how to anticipate a dive or a breach.
Orcas in Iceland
Orcas (killer whales) are seen around Iceland in several seasons. In summer, groups often feed around the Westman Islands off the South Coast. In winter, they have followed herring into fjords on the Snæfellsnes peninsula and elsewhere in the west, giving boat trips from towns like Grundarfjörður some of the most dramatic sightings of the year. Their movements follow the fish, so sightings vary a lot from year to year.
Seals in Iceland
Two seal species breed in Iceland: the harbor seal and the gray seal. Several Arctic species, including harp, ringed and hooded seals, appear occasionally as visitors. Seals haul out on beaches, sandbars and rocks, often in large groups.
The best places to see seals are the Vatnsnes peninsula in the northwest, Ytri Tunga beach on Snæfellsnes and Jökulsárlón glacier lagoon, where seals swim among the icebergs and rest on the ice floes. Keep your distance, stay quiet and never get between a seal and the water. Disturbed seals waste energy, and mothers can abandon pups.
Fish and life in Iceland's rivers and seas
The waters around Iceland are some of the richest fishing grounds in the North Atlantic, which is why fishing has shaped the country's economy and history. Cod, haddock, herring, capelin and mackerel feed the whales, seals and seabirds you come to see, and they end up on restaurant menus across the country.
Iceland's rivers are famous for Atlantic salmon, and fly fishing on rivers like those in the west and northeast draws anglers from around the world each summer. Arctic char and brown trout live in lakes such as Þingvallavatn and Mývatn. Even in Reykjavík, salmon run up the Elliðaár river, which flows through a green valley on the city's east side.
Icelandic horses
The Icelandic horse is one of the oldest and purest breeds in the world. Settlers brought small, sturdy horses from Norway over a thousand years ago, and strict rules have kept the breed isolated ever since. Importing horses into Iceland is banned, and a horse that leaves the country can never return, which protects the breed from disease.
Icelandic horses are known for their thick manes, calm nature and two extra gaits, the tölt and the flying pace. You will see them in fields all over the country, and many farms offer riding tours for beginners. In the north, a visit to an Icelandic horse farm near Akureyri pairs time with the horses with a walk in Vaglaskógur forest.
Remember that the horses in roadside fields are privately owned. Do not feed them, and never stop on the road to take photos.
Sheep and other farm animals
Sheep are everywhere in rural Iceland. In summer, they roam freely across the mountains and highlands, often in small family groups of a ewe and two lambs. In September, farmers round them up in the réttir, a traditional fall gathering that is still a big community event.
Drivers need to watch out for sheep on the roads, especially on gravel roads in the countryside. Lambs often stand on one side of the road and their mother on the other, and they may dart across without warning. Icelandic goats, a rare breed descended from the settlers' animals, can be seen at a few farms, including a conservation farm in the west.
Are there mosquitoes in Iceland?
For almost all of its history, Iceland had no mosquitoes. That changed in October 2025, when an amateur insect enthusiast caught three mosquitoes in Kjós, a rural area north of Reykjavík. As Yale Environment 360 reported, the insects were identified as Culiseta annulata, a cold-tolerant species, and it was not yet clear whether they could establish a permanent population.
For visitors, mosquitoes are still not a practical concern. What you may meet instead are midges, especially around Lake Mývatn, whose name literally means "midge lake." Most of these midges do not bite, but on calm summer days, they can gather in large swarms, and a head net makes walks around the lake much more pleasant.
Are there snakes in Iceland?
No, there are no snakes in Iceland. There are no native reptiles or amphibians of any kind, so you will not find snakes, lizards, frogs or toads in the wild. The cold climate and the island's isolation mean they never established themselves here, which makes Iceland one of the most relaxed places in the world to hike off-trail, at least as far as wildlife is concerned.
Are there any dangerous animals in Iceland?
Iceland has no dangerous land animals. There are no bears, wolves, venomous snakes or large predators living here. The biggest wildlife risks are minor: Arctic terns that dive at your head near their nests, and the occasional sheep that runs in front of your car.
The real dangers in Iceland come from nature itself rather than animals, including sneaker waves, glaciers, changeable weather and river crossings. Before any adventure, check the conditions and plan accordingly.
Insects and spiders in Iceland
Iceland has far fewer insects than mainland Europe, but it is not insect-free. You will see flies, beetles and moths, and several species of bumblebee buzz around gardens and wildflowers in summer. Spiders live here too, mostly small species, and none of them are dangerous to people.
Ticks are rare in Iceland and are not considered a significant health risk, which is another reason hiking here feels so relaxed. Wasps arrived in the 20th century and are now found in and around towns in late summer, so look before you take a sip from an open drink outdoors.
Wildlife by season in Iceland
What you see depends a lot on when you visit. Iceland's wildlife calendar follows the sea, the birds' breeding season and the snow.
In spring, from April to May, migrating birds return. Puffins arrive at their cliffs, golden plovers announce the end of winter, and whale numbers start to rise as the sea warms. Reindeer are often still in the lowlands of the east in early spring, which makes them easier to find.
Summer, from June to August, is peak season for almost everything. Puffins and other seabirds crowd the cliffs, whale watching is at its best, seals haul out with their young, and lambs and foals dot the farm fields. Arctic terns are nesting and will defend their territory loudly.
In fall, from September to October, puffins have left, but whales are still common, and the sheep roundups bring farm life into focus. In winter, from November to March, wildlife is harder to find, but you can still see seals, whales in some fjords, and reindeer and foxes against the snow.
Best places to see wildlife in Iceland
If you want to build a trip around wildlife, these areas give you the best chances:
The Westfjords for Arctic foxes, puffins, seals and bird cliffs
Húsavík and Eyjafjörður in the north for humpback whales
East Iceland for reindeer and the puffin colony at Borgarfjörður Eystri
Snæfellsnes and the Vatnsnes peninsula for seals
The South Coast and Westman Islands for puffins
Reykjavík's Old Harbour for year-round whale watching
Wildlife watching tips
A few habits make wildlife watching better for you and for the animals:
Use binoculars or a zoom lens instead of walking closer
Stay on marked paths near bird cliffs, where edges can collapse
Keep noise down near seals and nesting birds
Never feed wild animals or horses
Drive slowly in the countryside, where sheep often wander onto the road
Choose responsible tour operators who follow wildlife guidelines
The best time of year depends on what you want to see. Summer is best for puffins, whales and birdlife, while winter is better for reindeer in the east and for orcas following herring in some fjords.
Frequently asked questions
What animals live in Iceland?
Iceland's wildlife includes the Arctic fox, reindeer, mink and mice on land, plus more than 20 species of whales and dolphins, harbor and gray seals, and dozens of bird species, including puffins. Domestic animals like Icelandic horses and sheep are also common.
Are there polar bears in Iceland?
No. Polar bears do not live in Iceland. A few drift over from Greenland on sea ice, and just over 600 have been recorded since human settlement, but sightings are rare, and you will not see one on a typical trip.
Are there mosquitoes in Iceland?
Practically no. Mosquitoes were found in Iceland for the first time in October 2025, but it is not yet known whether they can survive long term. Biting insects are not a concern for most visitors, although midges can swarm around Lake Mývatn in summer.
Are there snakes in Iceland?
No. Iceland has no snakes and no native reptiles or amphibians at all. The climate is too cold and the island too isolated for them to have established themselves.
Where can you see Arctic foxes in Iceland?
The best place is the Westfjords, especially the Hornstrandir Nature Reserve, where foxes are protected. The Arctic Fox Center in Súðavík is also worth visiting for its exhibits about the species.
When is the best time to see wildlife in Iceland?
Summer, from about May to August, is best for puffins, birdlife and whales. Winter is better for seeing reindeer in East Iceland and, in some years, orcas following herring into fjords.
See Iceland's wildlife
Iceland may be short on land mammals, but its coasts and seas more than make up for it. Pick your season, head to the coast and bring binoculars. If you only have time for one wildlife experience, make it a boat trip. A whale and puffin cruise from Reykjavík gives you a real chance of seeing whales, dolphins and seabirds in a single afternoon.
